<h3>Create a YUI Instance</h3>
<p>We create a YUI instance and use <code>io-base</code> for this example, since we only need to basic IO functionality:</p>

<h3>Create Handlers for Global and Transaction Events.</h3>

<p>
We will create one object to handle the Global Events, and one object to handle Transaction Events.  Each object defines methods to handle the events in a transction's lifecycles.
The results are logged to <code>&lt;div id="container"&gt;</code>.

IO request, based on which button was clicked.
